It's 10 actually, I can leave out a space.
sed -e32d filename
Also, yours is 12 keystrokes. And once we get to multiple files, yours grows linearly, mine is constant.. :^)
for F in *;do sed -e32d "$F";done
(NB: a loop is necessary since we'll otherwise only delete the 32nd line of the first file.)
Makeshifts last the longest.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
